肌球蛋白结合蛋白-C(MyBP-C)是横纹肌的一个辅助蛋白家族,通过与粗肌球蛋白和细肌动蛋白的直接相互作用,参与粗肌丝的组装和稳定,并调节肌动球蛋白跨桥的形成。三种不同的MyBP-C亚型的特点是:心脏,骨骼肌,骨骼肌和骨骼肌。心脏MyBP-C(cMyBP-C)基因中的许多突变与家族性肥厚型心肌病(FHC)相关,并导致对心脏亚型的调节和作用的兴趣增加。本文综述了MyBP-C在心肌和骨骼肌中与肌球蛋白和肌动蛋白丝的相互作用及其在调节收缩性中的作用。
Myosin-Binding protein-C (MyBP-C) is a family of accessory proteins of striated muscles that contributes to the assembly and stabilization of thick filaments, and regulates the formation of actomyosin cross-bridges, via direct interactions with both thick myosin and thin actin filaments. Three distinct MyBP-C isoforms have been characterized; cardiac, slow skeletal, and fast skeletal. Numerous mutations in the gene for cardiac MyBP-C (cMyBP-C) have been associated with familial hypertrophic cardiomyopathy (FHC) and have led to increased interest in the regulation and roles of the cardiac isoform. This review will summarize our current knowledge on MyBP-C and its role in modulating contractility, focusing on its interactions with both myosin and actin filaments in cardiac and skeletal muscles.
